The Puyehue-Cordon Caulle volcano in southern Chile erupted on Saturday, spewing ash up to six miles high and forcing the evacuation of 3,500 people. Winds carried the thick ash plume as far as 62 miles away to the town of San Carlos de Bariloche in Argentina, coating it in grey ash and sulfur fumes. The eruption prompted the closure of borders between Chile and Argentina and warnings for local residents to remain indoors due to the heavy ashfall.
